In this study, we explored the regulatory role of microRNA miR-101-3p on the zinc finger protein 746 (ZNF746), also known as PARIS, which is implicated in both sporadic and familial forms of Parkinson's disease. In a Parkinson's disease cell model, utilizing SH-SY5Y cells treated with 1-methyl-4-phenylpyridine (MPP+), we observed that miR-101-3p was downregulated, while ZNF746 was upregulated. To investigate the direct impact of miR-101-3p on ZNF746, our team conducted overexpression experiments, successfully reversing ZNF746's expression at both the mRNA and protein levels, as confirmed through quantitative PCR and western blotting. We also performed luciferase assays, providing compelling evidence that ZNF746 is a direct target of miR-101-3p. Additionally, we noted that miR-101-3p overexpression resulted in increased expression of PGC1α, a gene targeted by ZNF746. Functionally, we assessed the implications of miR-101-3p overexpression through MTS assays and flow cytometry, revealing significant promotion of cell viability, inhibition of ROS production, and reduced apoptosis in the Parkinson's disease cell model. In conclusion, this study highlights the role of miR-101-3p in regulating ZNF746 expression and suggests its potential as a therapeutic target for Parkinson's disease. These findings provide valuable molecular insights that could pave the way for innovative treatment strategies in combating this debilitating neurodegenerative disorder.
在本研究中,我们探究了微小RNA miR-101-3p对锌指蛋白746(ZNF746,也称为PARIS)的调控作用,该蛋白与散发性和家族性帕金森病均有关联。在帕金森病细胞模型中,利用经1-甲基-4-苯基吡啶(MPP+)处理的SH-SY5Y细胞,我们观察到miR-101-3p表达下调,而ZNF746表达上调。为研究miR-101-3p对ZNF746的直接影响,我们团队进行了过表达实验,通过定量PCR和蛋白质印迹法证实,成功在mRNA和蛋白质水平逆转了ZNF746的表达。我们还进行了荧光素酶测定,提供了令人信服的证据表明ZNF746是miR-101-3p的直接靶标。此外,我们注意到miR-101-3p过表达导致ZNF746靶向的基因PGC1α表达增加。在功能方面,我们通过MTS测定和流式细胞术评估了miR-101-3p过表达的影响,发现在帕金森病细胞模型中显著促进了细胞活力、抑制了活性氧生成并减少了细胞凋亡。总之,本研究突出了miR-101-3p在调节ZNF746表达中的作用,并表明其作为帕金森病治疗靶点的潜力。这些发现提供了有价值的分子见解,可为对抗这种使人衰弱的神经退行性疾病的创新治疗策略铺平道路。
